“…Recently, research on this class of materials has increased, since these compounds are used in different range of applications. They have attracted a lot of attention due to their magnetic and electronic properties, including half metallicity, ability to support superconductivity [5], low eld magnetoresistance (LFMR) [6][7] and a variety of magnetic structures [8]. All these properties have made this type of materials promising in the technological eld such as in hard drives, nonvolatile magnetic random access memory (MRAM) [9] and spintronic devices [10].…”

The structural, elastic, electronic and magnetic properties of cubic double perovskite Pb2FeTaO6 have been investigated using self-consistent ab-initio calculation through full-potential linearized augmented plane wave (FP-LAPW) method within the frame work of the spin-polarized density functional theory (DFT), considering generalized gradient approximation (GGA) described by Perdew–Burke–Ernzerhof (PBE), GGA+U and mBJ-GGA. Pb2FeTaO6 is found as ductile material from the elastic calculations. The obtained magnetic results show that Pb2FeTaO6 is stable in the ferromagnetic state; the electronic properties show a half-metallic behavior using GGA and GGA+U and a semiconducting one with TB-mBJ, magnetic moments of each atom are also discussed in this study. These results confirm the use of this compound in spintronic devices.

“…The field of superconductivity was revolutionized almost immediately after the publication of the author's original two papers on the chemical bonding topology of superconductors 9,10 when the first high T c superconducting copper oxides were discovered. − Subsequent development of the chemistry of high T c superconducting copper oxides led to superconductors with T c s as high as 130 K, a considerable improvement of the maximum T c of only ∼20 K in the days before copper oxides. Shortly after the recognition of certain copper oxide structures as high T c superconductors, the author showed how the idea of a porous conducting subnetwork, developed by consideration of the Chevrel phases 9 and the ternary rhodium borides, could be extended to the copper oxides …”

Consideration of the chemical bonding topology of the conducting skeletons in the Chevrel phases MMo6S8 and the lanthanide rhodium borides LnRh4B4 indicates that the conducting skeletons consist of networks of edge-localized bonded atoms. These observations suggest that superconductivity is favored when electron mobility is restricted to fewer than three dimensions. Thus, the chemical bonding topologies of the highest T c superconductors contain one of the following features: (1) edge-localized M−M bonding in the conducting skeletons of ternary and quaternary solid-state superconductors or related, partially localized bonding in superconducting transition metals and their alloys; (2) localized rather than fully delocalized bonding in copper oxide superconductors containing Cu−O−Cu linkages with appreciable Cu···Cu antiferromagnetic interactions; or (3) surface-localized bonding in fullerene superconductors containing direct C−C bonds such as K3C60. In addition, heavy fermion superconductors with considerably lower T cs values are known in which the conducting skeleton consists of variable oxidation state lanthanide or actinide cations diluted by an anionic network of other metal atoms so that the lanthanide or actinide atoms are not within bonding distance of each other.

“…Di-and poly-nuclear metal complexes of hydrazonic ligands play a significant role in the study of multi-electron redox reactions, magnetic exchange interactions and intramolecular binding [21,24]. Acylhydrazone and semicarbazone derivative compounds occupy an important position as ligands in metal coordination chemistry, because this general class of chelating agents shows different stereochemistries and nuclearity in complexation with transition metal ions [4,16].…”

The coordinating properties of a new bis(pyridylhydrazone) ligand derived from iminodiacetic acid diethyl ester and 2-pyridinecarboxaldehyde (picolinaldehyde) H 3 Imdp and of the bis(salicylhydrazone) H 5 Imds and H 4 MeImds ligands derived, respectively, from iminodiacetic acid diethyl ester and from methyl-iminodiacetic acid diethyl ester and salicylaldehyde were considered, by means of analytical and spectroscopic methods, towards first row transition metal ions. These ligands showed various coordination modes in complexation with Cu(II), Co(II), Mn(II) and Zn(II) ions. In particular, we have synthesized and characterized, by analytical, 1 H NMR and IR techniques, tri-, di-and mononuclear metal complexes
